love the contrast of 'no name cargo ship' with the rich resonance of her name Carmen. And the view out of the porthole. Funnily enough I'm not quite so sure about the last line. Why are the needles clacking behind her?

This is creepy. I actually liked the last line, because we knew she was a 'stowaway' on the ship, ordered to stitch patches for clothing. To have her looking out the portholes, listening to the needles stitch the tune of her mind, lends to longing and hope, despite her nightmares, both past and present. Good work.
